John Stamos Shows Off His Fit Body at 62 with a Rooftop Shower Picture

John Stamos rang in his 62nd birthday with the kind of confidence most people half his age would envy — sharing a rooftop shower snapshot that quickly reminded the internet why he's been a heartthrob for decades.

John Stamos marked his 62nd birthday on August 19, 2025 by showing off his ageless physique. The "Full House" alum treated fans to a bold photo of himself wearing only black Calvin Klein briefs while enjoying an outdoor rooftop shower.

"A rooftop birthday shower in NYC to start the day, and the love of family and friends to carry me through," he captioned the steamy shot. "At 62, I've learned the best things in life can't be washed away…laughter, love, and gratitude. Thank you for every wish and every year. I don't take a single drop for granted," he added.

Stamos's shirtless moment highlighted his toned abs and muscular biceps, proof of the fit lifestyle he has maintained well into his sixties.

He has been open about what keeps him grounded and healthy, crediting his sobriety — a journey he began a decade ago — and the joys of fatherhood. He shares his 7-year-old son, Billy, with his wife Caitlin McHugh, whom he married in 2018.

Beyond family life, Stamos keeps busy with creative pursuits. He continues to perform with the Beach Boys in between film and television projects, and he released his bestselling memoir, "If You Would Have Told Me," in 2023.
